So... this flat, "issue" ... does this bike ( nano ) have the skinny rubber rim strip, that most your avg. bikes from china ( pacific owned ) have ?

Yes, it has a rubber band that slides to one side or the other. I took them off and installed tape.

Well, heres mine :

Re-tape-ed & re-cabled ( shorter housing in white ), old school Vetta saddle, Schwinn xs bmx pedals, Elite cage, 8mm crank bolts.

Congrats, they are a lot of fun.

The "before" :

I bought rim tape, and a new set of handlebars for mine. I can't wait to get them on.

" Real " upgrades, next pay check... these will have to do, for now.

I like the white cable housing.

Oops. I bought new rim tape saturday, but didn't install it. I had a rim tape failure tonight... Well there's my excuse to go hog wild and get this bike in Nero-shape.

New upgrades:

-Found a magic gear of 47x13, allowing me to lose the derailleur-mounted chain tensioner (Rocket BMX 10H 47T chainring, Dimension 13T BMX cog, KMC Z610HX single-speed chain).
-Origin8 quill stem adapter w/ 80mm Civia Bryant stem.
-Intense Micro Knobby-R tires.

Looks good!! What is the total weight?

Nano in front of my "retro" allez ... must be a funny angle, since the allez is a 52 and the nano is a 53.



... & new cinelli zebra tape.

Mine arrived last night. I have two bike projects splayed all over the basement that need cleaning up tonight before I get started, but that's some motivation right there!

How does "one" calculate GI fora 20" wheel ?

Choose "44-406" for the tire size:

Thanks, no java on this comp... https://sheldonbrown.com/gears/ : o)

Looks like, these little guys will never be *fast* ... : o( ... not even with a 56/11.

Raised my FD. : o)

Had some free time ... an x-330 dontated parts, along with an old college franken bmx commuter.

52/12 ... with a 48 inner. This is ~90 gi, at 90 c/rpm, thats 24 mph. Much better, then the stock gearing, ( 20 mph @ 90c ) maybe now the tires are the next speed factor/excuse . ( link just in case https://www.thorusa.com/ )

I also had a chance to weigh it . : o(


... I'll find out on tomarrows commute.

Built mine up last night. 53cm size, no modifications except I took the wheel reflectors off, bathroom scale method says 26.6lbs. It was sooo hard not to stay up late last night and start swapping stuff around. I have at least two double cranks in the basement that would look better on this bike, not to mention a triple if I wanted to give this thing some rock crawling gears. I have a threadless stem adapter just begging to be installed with a nice shiny alu stem that should give me enough length to replicate body position on my good road bike. I have bar end shifters (and an 11X34 9sp cassette) that need using. The list goes on. I'll probably just do the rim strips and go get some initial ride impressions first. This thing is going to be a riot.

Morning commute, pit stop ...

( *note*: chain length, oops . )

Fixed the chain length issue, on lunch ...

but, not with a longer chain ... instead I made a tiny franken cassette. : o)

I used a Forte(hope it lasts) 11-32 ...AND, a Sram 12-23 .

So... I now have a 11-21, 8 sp ! ( 11,12,13,14,15,17,19,21.)

Shifts suprisingly well, considering the sloppy ( indexed ) levers.

~98 GI with the 58T

The left-over cass/paper weight ... ( 12,14,16,18,21,23,24,28. )

451 wheels and skinnier tires may make it go even quicker.

Rim tape installed. Tires are sitting at 110psi. I feel like a big man, I got the wire bead tires on without tire levers. :-)

Current state ... and, stuff on order.

Love the white on black. Mine's black too and I'm thinking white all around. My only mods so far are rim tape and keo's (black, b/c that's what I have laying around). The corncob cassette is a great idea.
